Application filed. and... s, 1897.

Be itknown that we, JAMES TAYLOR and [JOHN F. FLAD, citizens of the United States,

especial novelty consisting in equipping a circular machine provided with latch-needles for this work; and to this end our invention. consists, first, of an improved attachmentwhereby the needles, inaddition to being raised and depressed by the ordinary cams attached to a cam-cylinder, are also depressed by rotatable disk-cams which are partially cut away on suitable portions of their peripheries, thereby forming recesses which enable one or more needles; as desired, not to be lowered as far down as those that come in contact with the outer edge of said disk-cam, the latter being caused to rotate in substantially a vertical plane and operative on the butts of the cylinder-needles, while the camcylinder revolves in a substantially horizontal plane around the needle-cylinder. I

It further consists of two stationary toothed rings or racks suitably supported, one of which contains more teethin number than the needle-cylinder has slots or needles, while the other of said racks contains less teeth than the needle-cylinder has slots or-needles,

that when the bevel-wheel 10 is rotated it Serial in. 618,452. (No model) corresponding to'those shown in Fig. 1, but

Fig. 5 represents a view of some of the parts shown in Figs. 3 aud t, but in different positionsfrom those in said figures; Fig. 6 represents a view of some of the parts shown in Figs. 3, 4, andl5, .65 but in different positions from those insaid z, figures. Fig; 7 representsaperspective'view of certain detached parts of the machine. Fig. 8 represents a side elevation of. a cam employed. Figs. 9 and 10 represent, respcd tively, views of the face and back of fabric" as produced by our machine. Similar numerals of reference indicate cor responding parts in the several figures.

. Referring to the drawings, 1 designates a needle-cylinder in which are placed theneedies 2, the latter occupying the grooves 3 in said cylinder in the usual manner. Only a portion of the needles employed are shown in Figs. 1 and 2, the others being omitted for the sake of clearness of illustration of'said figures, it being understood, however, that in practice all the grooves 3 have a needle 2 placed therein. I v

The needle-cylinderl is secured to the bed 4 of the machine by screws- 5, which firmly retain said parts in position, so'that when the bed a is sccuredtoa benchlor table 6, as in the present instance, by screws '7, only one of the latter being visible, as shown in. Fig. 2, all of said parts will be held firmly in juxtaposition, excepting, however, the needles 2, which are raised and lowered by means to be hereinafter described.

8 designates a cam-cylinder which is guided on the bed 4 of the machine in such manner as to permit said cylinder to rotate, and has on its under side the bevel-gear or rack 9, with which meshes the bevel gear-wheel 10 on the driving-shaft 11. It will be apparent will cause thecam-cylinder 8, with which it pose. to be hereinafter described and which may be secured in' any suitable manner to a shaft 19, which latter carries a gear-wheel 20,

I which is firmly secured thereto by a set-screw 21. The cam 18 is provided with recesses 20 and 21*, the objectof which will be hereinafter described The shaft 19 is journaled in an ear 22, which is secured to the cam-cylinder 8 by means of 1 screws 23, as seen in Fig. 1; it being evident that said ear 22 and its adjuncts will be carried around by the cam-cylinder when the latter rotates. v

The gear-wheel 20 meshes with a toothed ring 24, which is secured to an annulus 25, which latter is secured to the bed 4'of the machine, it being noticed that the toothed ring 24 remains at all times stationary and that the gear-wheel 20, which meshes with the same, is carried around said ring by the cam-cylinder 8, so as to cause quently the rotary cam to rotate, for a' purpose scribed The toothed ring 24 is provided with ears 27, in each of which is a slot 28, through which is passed a screw 28 [shown in dotted lines in Fig. 1,) which enters a threaded opento be hereinafter deing 29 in the annulus 25, so as to retain said ring 24 in position on' said annulus. The slots 28 permit the ring 24 to be moved slightly in the direction indicated by the arrows a and b in Fig. 1 in order to adjust said ring relatively to the needles 2, and thereby properly time the cam 18 with respect to said needles.

7 30 designates. a gear wheel secured to a shaft 35 by a set-screw 35 and which meshes with a toothed ring 31, the latter being se-.

cured to the annulus 25 by screws 31 (shown in dotted lines in Fig. 1) and whose threaded portions enter threaded openings 36 in the annulus 25. The object of the gear-wheel 30 and toothed ring 31 is to impart motion to a rotary cam 34, secured in any suitable manner to the shaft 35 of the gear-wheel 30, for a purpose to be hereinafter described.

The ring 31 is provided with cars 32, in each of which is a slot 33, through which is passed one of the screws 31*, which secures said ring 31 to the annulus 25.

The object of the slots 33 isto permit the ring 31 to be adjusted relatively to the needles 2 and which may be done by slightly moving said ring in the directions indicated by the arrows c and (Z in Fig. 1. The adjustment of the ring 31 relatively to the needles .2 is necessary, so as to properly time the cam 34 with said needles.

The shaft 35 is journaled in an car 37, which the shaft 19, and conse- 18, secured thereto,

(see Fig. 2,) from which through a is secured to the cam-cylinder 8 by screws 38 and is carried around. by said cylinder 8, so

as to cause the shaft 35 and the cam 34 there:

on to'rotate, for a purpose to be hereinafter described. I

The cam 34'(best seen, in Figs. 1 and 8) is formed with the working faces 39 and 40 and recesses 41 and 42, the object of all of which will be hereinafter described.

The butts 44 of the needles 2 are preferably formed of cylindrical shape, so as to strengthen the same. (See Figs. 1 to 6, inclusive.)

'Pivoted, as at 45, tothe camcylinder '8 (see Figs. 3 to 6, inclusive) is a cam 46, which latter is adjacent to the cam 15 and is adapt with the latter, for a-- 5 ed to act in connection purpose to be hereinafter described." The;

cam 46 is held in its normal position by a spring 47, whose bent portion 48 bears upwardly against the under side of the same. (See Figs. '3 to 'Z, inclusive.) The spring 47 :is secured in any suitable manner to the outer face of the wall of the cam-cylinder 8 and its bent portion 48 is passed through a slot 49 in the wall of said cylinder and projects beyond the inner face of the wall of the latter, so asto contact with the under side of the cam 46, for a purpose to be hereinafter referred to.

The cam-cylinder 8 is "provided with yarnguides 8 through the eyes of which passes the yarn 5O asdelivered from cops or bobbiils'50 (See Fig. 3.) The yarn 50 after leaving the eyes of the usual manner, said needles taking the yarn at points over the cams 51 and 13.

The operation is as follows: The yarn50,

Figs. 9 and 10 is from any desired number of bobbins or cops and is fed to the needles 2 in the usual man- It will be evident that the fabric as consist of ner. produced by this machine may yarns which are all of'the same color, or it may contain yarns of different colors, according to the design. The cam-cylinder 8 in rotating will cause the needles 2 to be .raised and lowered, so as to'form loops which interlock with each other and produce a knitted fabric. When the butt 44 of a needle 2 is on the apex 51 of the cam 12, (see Figs. 3 and 4,) that needle is then at-lits' maximum height and in a position to receive the yarn which is to be drawn by the beardjor hook 52 of said needle loop on the latter in the usual manner. A loop through which the yarn 50 is drawn in the processof knitting and which forms part of the fabricshownin Figs. 9 and 10 is not shown in the drawings, as this is deemed unnecessary, since this feature of the operation is old and common in all knitting-machines. The cam-cylinder S is 1'0- tated by the mechanism hereinbefor'e described and moves in the direction indicated by the arrows at in Figs. 3 to 6, inclusive. The cam-cylinder 8 in rotating will cause the the yarn guides 8 is brought under the latches of the needles 2 in the fabric shown in produced, may be obtained v der 8.

. butts 44, and consequently the needles 2, to be raised by the portion 51 of the cam 12, so that said needles may receive the yarn from cop and form the same into loops in the "ocess of knitting. The butts 44 of the eedles 2, which were raised by the portion of the cam 12,- are next'oaused to contact i the under side of the cam 14, which de-' sses said butts, and consequently the nee- 2,.so;a s to bringthe butts 44 in the path therotary cam 18. The working faced?) :1 contacts with the butts 44 and depresses ame, and consequently the needles 2, as n in Fig. 3, and brings said butts 44 path of the cam 15, which depresses ntts 44 to their full extent, and thereby s the needles 2 to draw the yarn 50 in hes in the usual manner in the process .nitting. -The needles 2 are next raised, re to their butts 44 contacting with, the king faces of the cams 13, so as to again s said needles in a position to have the n 50 passed under their hooks 52, so that .id yarn may be drawn through the loops .1 saidneedles and form additional loops in e process of knitting. After the cam 13 has left the butts 44 of the needles 2, which were raised by the same, said but-ts contact with the under side of the cam 16, which depresses said butts 44, and consequently the need 2, to thei full extenhiso as toagain.

forin loops in the fabric. When the cam 16 left the butts 44, the latter next contact with the working face of the cam 12 and are raised by the same, and thn's'brought in a position similar to that shown at I), (see lefthand portion of Fig. 3,) but in another portion of the cylinder 8. The butts 44 of the needles 2, which are to be acted upon by the recesses and 21 are so timed relatively to said recesses that when said butts 44 leave the cam 14 they are caused to enter said recesses, due to the rotation of the cam-cylin- The butts 44, which enter the recess 20 will be brought into the position shown in Fig. 4 when the cam 18 has been rotated ninety degrees, it being noticed that said butts 44, and consequently the needles 2, have not been depressed sufliciently to form loops in the fabric. -A further rotation of ninety degrees of the cam 18 will bring the butts 44 from their positions seen in Fig. 4 to that shown in Fig. 5, so as to place said butts in the path of the cam 46, so that said butts 44, and consequently the needles 2, may be raised to their full extent by said cams in-order that said needles may be brought in position to have the yarn enter their hooks 52 and be drawn by the same through loops on said needles in the usual manner in the.

hooks 52 through aloop on each of said in Fig. 10.) The butts 44 after leaving the cam 40 and theupper portion of the cam 15 contact with the working faceof the cam 17 and are thereby brought in the path of the cam 16 and from this point travel in the same course described in connection with the neeto those bearing the; numerals 12 to 17, in-

elusive, "and: as their functions are precisely the same a detailed description of said camsis not deemed necessary.

It will be evident that the working face 18 and recess 21 of the cam 18 produce results 43 a slight distance to one side of and above the floats formed by the previous revolution of said cylinder and in the row of loops immediately beneath them, and thereby cause said floats 43 to lie in diagonal lines, as clearly shown in Fig. 10. ltis also'essentialthat the teeth in the inner ring 31 shall exceed the number of needles 2 in the cylinder 1, so that' the floats 43 produced by the recesses 41 and 42 of the cam 34 shall be made to occupy a position a little to one side of and just above the floats 43 previously produced by the revolution of the cam-cylinder 8 and in the row of loops immediately beneath it, and thereby cause said floats 43 to lie in diagonal lines which cross those formed by the recesses 2O and 21 It will be evident that the number of recesses in the cams 1S and 34 may beincreased or diminished, according to the design of the fabric.

Should any of the butts 44 of the needles 2 strike the corner 44? of the cam 46, which may sometimes occur, instead of striking said cam at a point below said corner, no injury to the needles or machine can result therefrom, as the spring 47 will yield and permit said cam to assume the position shown in Fig. 6, and thereby bring the corner 44 above the butt 44, which latter will then be deflected by the lower portion of the cam 46, so as to cause said butt 44 to pass under the cam 15, for the purpose hereinbefore.described. I

The working faces and recesses in the cam 18 are so timed'relatively to similar parts in the cam 34 that when a working face on the cam 18 depresses the butts 44 of the needles 2 a working face on the cam 34 will likewise depress the'butts 44 in its path, and the effect produced entire-butts 44 by said working faces will occur attire same moment. Each recess The cam 34 works in con- .JHIIOBIOI] wlth cams similar in every respect exist in practice,

in Fig. 2 for the purpose hereinbefore stated. 4

in'the cam 18 is so tiined relatively to similarparts in the cam 34 that they operate in unison on the butts 44: of the'needles 2, for the purpose hereinbefore' described.

As hereinbefore stated, the working faces as do the can; 18 in Fig. 21s represented as depressing a butt 4A: of a needle 2, while the cam 34 in said Fig. 2 isrepresented as having one of its recesses acting upon a butt 44. This position of the working face in the cam 18 relatively to the recess in the cam 84 would not but this has been shown so described our invention, w'hat Having thus and desire to secure by Letwe claim as new, ters Patent, is" a 1.
